■ Select 4) to toggle the SCSI reset operation between YES and NO.

When set to YES, the bridge will automatically reset each SCSI bus after

initial power-up and after reboots.

■ Select 5) to change the discovery delay time for SCSI devices. This is

the time that the bridge waits after a power-up or reboot before starting to

discover SCSI devices. This value should be set to no less than 250 ms,

according to the SCSI standard for reset-to-selection time. HP recommends

that you set the value to at least 2 seconds to ensure all SCSI devices

complete their individual power-ups.

■ Select 6) to toggle Initiator Mode Buffered Tape Writes. Tape Buffered

Writes return status on consecutive write commands prior to the tape

device receiving data in order to enhance performance.

— Initiator mode is used with Fibre Channel hosts writing to SCSI tape

devices.

■ Select 7) to toggle Target Mode Buffered Tape Writes. Tape Buffered

Writes returns status on consecutive write commands prior to the tape

device receiving data in order to enhance performance.

— Target mode is NOT supported in HP tape libraries.

■ Select 8) to toggle the SCSI termination mode between Internal and

External. This option is only available on the FC 2/1 LV model. The FC 4/

1 HV model is automatically set to internal termination only. The internal

setting allows the bridge to internally terminate a SCSI connection. Setting

this option to External requires the SCSI Bus, not the bridge, to handle

SCSI termination.

Note If both connectors of either SCSI bus on the FC 2/1 LV are to be

used, it is important that this configuration setting be changed to

External for that particular bus. Be sure proper termination is in

place at each end of the SCSI bus.
